Speaking of Pinnacle, right now I am trying to make a movie from a few
thousand jpeg images. This is a feature in the program, and does work.
There are a few probable bugs though - the program has just crashed
for the 3rd time this morning, trying to render the movie.

One thing I use Pinnacle Studio 9 for is to create slideshows. There is
a
workaround for your problem Instead of trying to render the whole
project
at one time, break it down into smaller parts (say 500 or 1000 jpegs).
Render
those as AVI files and then use those as the source for our final
project.
That way, Studio will treat it as just another video file rather that
1000's
of individual frames.
